Evaluation of Chikungunya Virus Surveillance System in Chaiyaphum Province 2020

Abstract

A cross-sectional study was conducted. The objectives of the study were to measure the quantitative attributes and qualitative of surveillance systems. Then, we recommended improving them. Five hospitals namely; Nong Bandung, Kasetsomboon, Chatturat, Nong Bua Rawe, Phukhieo, and two communities were studied. The study population and sample were the persons who visited those hospitals between 1 October 2019 and 30 September 2020. About 419 of 1,332 patients' medical records were review. Moreover, the data of 102 of 766 persons who lived in households found the Chikungunya virus from 1 October 2019 to 30 September 2020 were collected. And also, the data of 31 public health providers were collected. The result found that sensitivity in hospitals and community was 36.84% and 12.64% respectively. Positive predictive value and timely were 100% and 71.43% respective. The information between patients' medical records and the R506 was not consistent. The result found that health care providers agreed that chikungunya disease was required to report, but they did not know probable cases needed to report too. Only cases with confirmed laboratory were reported. The reporting system was flexible because it had many channels for communication. In conclusion, positive predictive value was at a good level, but sensitivity in hospitals and communities needed to improve. The quality of data was good, we recommended that they needed to increase the report in time for controlling the pandemic. Definition and guidelines for reporting chikungunya disease should be communicated for all hospitals. And it should be surveillance along with dengue hemorrhagic fever that provincial administrators pay attention to.
